SEPARABLE BUTTON.

Specification of Letters Patent.

Application filed July 20, 1911. Serial No. 639,515.

To all whom it may concern:

Be it known that I, Eusrm A. PHINNEY, a citizen of the United States, residing at 287 High street, Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Separable Buttons, of which the following is a specification.

My invention relates to improvements in separable buttons and consists specifically of a further improvement in the front or separable member of the button described in Letters Patent-of the United States, No. 918,588, issued to me April 20, 1909.

The purpose of my further improvement shown in this application is to provide a more effective method of securing the separable portion of the button to the main portion or back thereof. I accomplish this im-; provement by the mechanism shown in the accompanying drawings, in which Figure l is a perspective of my improved Fig. 2, a view of the separable portion of the button with the locking attachment placed therein. Fig. 3, a cross section through the plane of w--x of Fig. 2. Fig. l, a vertical section through the entire button showing the separable part of the button locked to the back portion thereof; and Fig. 5, a like vertical section showing the locking attachment released.

The same parts of my device are indicated by similar lettersthroughout the various views. I

In Fig. 1, ri -a are limbs of a V shaped locking device, the two side members of which are normally separated by the V shaped space a. These limbs terminate at the upper portion in the flat ends o*a*,

these ends being somewhat larger than is the main body of the arms, and by the bev' cling of the upper and outer portion of the limbs o -c as shown by aa the'outer edges mm of the top surface aa are left somewhat wedgeshaped. At the lower extremity the locking device is reduced in size as shown at a -a leaving the somewhat bulbous end a. I

Fig. 2 represents the separable portion "of the button and consists in substance of a hollow shank band a front 0. The shank contains a slot extending from the line a2m shaped locking member normally project outside of the slot 7) as shown in Fig. 2.

Fig. 3 is a cross section upon the line m-a of Fig. 2 and shows the slots bb of the shank Z), the beveled outer faces of the looking member being shown by (i -a.

In Fig. 4 is shown a vertical section of the entire button. It will be seen by reference to this figure that the entire base of the button, that is, all portions of the button excepting the member shown in Figs. 1, 2 and 3, are identical with similar parts of the button for which Letters Patent were granted to me, as hereinbefore stated,.and Figs; 4 and 5 are shown only for the purpose of describing the working of my improved attachment. In Fig. 4 the button is shown with the separable front C and its connecting shank locked within the base portion of the button by the outer edges m'm' of the V shaped member engaging the inwardly rolled and flattened margin f of the upper portion of the shank f. Fig. i also shows Patented Dec. 19. 51911. g

the upper portion of the shank b and its method of attachment to the front 0, although this attachment may be made in any suitable way.

Fig. 5 shows the method of releasing the button by pushing up the interior tube 03 of the releasing member, the upper portion of this tube serving by means of the beveled faces (Z301,3 of the V shaped member to bring the arms of the V together and thus release the upper portion of the V shaped member from engagement with the inwardly rolled locking rim of the exterior shank f.

The principal feature of my improvement, as will be seen, is theuse of two retaining points for the separable portion of the button instead of one, thus enabling the separable portion to be looked more securely to the base and serving further to hold the separable portion more steadily within the base, the locking engagement being opposed and thus balanced. The entire construction moreover made possible by the improvement shown in this present application is neater and stronger than that of my previous in vention.

Having now described my invention, What I claim and desire to secure by Letters Patent is V A separable button comprising in combination With'a hollow shank having a head a on one end and an interior annular shoulder at its other end, and a lock releasing tube telescopihg said hollow shank, of a button head, a hollow shank carried by said head to telescope the releasing tube, said hollow shank having transverse slots extending from a point near the outer end to a point near the inner end of the tube, and a vshaped locking member mounted in said hollow shank, said locking member com prising a pair of arms having enlarged. outer ends extending through the slots, the outer faces of: said enlarged ends being beveled outwardly and engaged by the releasing tube When the latter is forced inwardly to force said ends within the shank, the inner ends of said arms connected together and having depressions at a point beyond their connection, the said. hollow shank being compressed into said depressions for securing the locking member in the hollow shank. In testimony whereof I ai'llx my signature in presence of two witnesses.
